SPECIFICATION forming part of Letters Patent No. 553,845, dated February4, 1896. Application ned nach 15, 1895. serial No. 541,868. or@ model.)

To' aZZ whom' t may concern:

Be it known that I, CARL P. EICHLER, a citizen of the United States, anda resident of Cleveland, county of Cuyahoga, and State of Ohio, haveinvented certain new and useful Improvements in Flour-Sitters, of whichthe following is a specification7 the principle of the invention beingherein explained and the best mode in which I have contemplated applyingthat principle so as to distinguish it from other inventions.

The annexed drawings and the following description set forth in detailone mechanical form embodying the invention, such detail constructionbeing but one of various inechanical forms in which the principle of theinvention may be used. j

In said annexed drawings, vFigure I represents an axial section of myimproved i'loursifter, and Fig. II a top plan view.

The body A of the sifter is of the usual cylindrical form, having theusual sloping upper edge, to give it the form of a scoop, and providedwith the usual screen-bottom A. A handle-bail B, preferably formed froma strip of sheety metal, is secured with its ends to the low side of thebody. An open-work stirrer C rests upon the screen-bottom and haspreferably a substantially circular outline. Said stirrer may be formedfrom wire bent into serpentine or other open-work form, or it may be, asillustrated in the drawings, formed from a sheet-metal disk, cut outinto the form of a grate or other reticulate pattern. The stirrer isheld in contact with the bottom and is guided to have straight-linemovement over said bottom by a rod C having sliding bearing for its endsin the sides of the sifter-K body, and to which the stirrer is solderedor otherwise secured. That end of the rod which projects into the lowerend of the handlebail has a stop which is formed by the rod being bentat a right angle to form an open hook o. A movable handle D isyieldingly supported bya spring-coil d at its upper end in the upper endof the handle-bail, and has a pin d at its lower end, preferably formedby the end of the wire which forms the springcoil and which passesthrough the handle, which pin engages the hook of the stirrer-rod. Aspring E is provided Within the sifter-body and is connected to thestirrer-rod to return the stirrer after it has been drawn toward the lowside of the body by drawing the movable handle toward the handle-bail.An upward projection c is formed upon the stirrer-rod within thesitter-body and may be engaged by arms f radiating from a shaft F, whichis transverselyjournaled in the sitter-body and is provided with a crankf for revolving it. By revolving the crank-shaft the arms will be causedto strike the projection upon the stirrer-rod so as to force it backagainst the spring, which will again force the rod and stirrer forwardwhen the engaging arm slips off from the projection, whereby the stirrerwill thus be reciprocated.

The open hook at the end of the stirrer-rod will admit of the stirrerbeing reciprocated without moving the movable handle, which is generallygrasped together with the handle-bail when the sifter is in use.

The sifter can, on account of the provision Of the movable handle withinthe handle-bail, and the crank-'shaft7 be either held and actuated by'one hand, or be held by one hand and actuated by the other, accordingto the convenience of the person using the sifter.

The above-described sifter is one form of improvement and addition tothe style of sifter disclosed and claimed in United States Patent No.513,489, for a flour-sifter, granted to me on the 30th day of January,1894. In United States Patent No. 524, 892, for a sifter, granted to meon the 21st. day of August, 1894, I employed the movable handledisclosed in the former patent for the purpose of rotating a stirrerwhich was provided with an independent crank-shaft for rotating it, sothat the sifter might be operated by the one hand grasping thehandle-bail, by reciprocating the movable handle, or might be held byone hand grasping the handle-bail while the stirrer was rotated byturning the crank-shaft with the other hand. In the present form ofsifter, forming the subject-matter of this application, the stirrer isreciprocated by either reciprocating the movable handle or by revolvingthe crank-shaft. Quicker and more effective action of the sifter isaccomplished by the stirrer being reciprocated and returned by a springthan by the stirrer being rotated, particularly as the stirrer isreturned with a jar by the action of the spring.

IOO

Other modes of applying the principle of.' my invention may be employedfor the mode herein explained. Change may therefore be made as regardsthe mechanism thus disclosed,provided the principles of construction setforth respectively in the follmving claims are employed.

I therefore particularly point out and distinctly claim as myinventionl. In a flour-sifter, the combination of a sitter-body, areciprocating stirrer upon the screen-bottom of the body, a movablehandle connected to said stirrer to move it in one direction and toadmit of it being independentl7 moved, a spring for returning thestirrcr, and a shaft journaled in the sitter-body and constructed tomove the stirrer against the action of its spring when said shaft isrevolved, substantialljv as set forth.

2. In a floursifter, the combination of a sifter-body; a movable handle;a reciproca ing stirrcr upon the screen-bottom of the body, providedwith an open connection with the handle to adm it of the latter movingthe stirrer in one direction and of permitting the stirrer to moveindependently, and provided with an upward projection g a springconnected to the stirrer to return it; and a rotary shaft inthesifter-body provided with a cani which engages the projection of thestirrer, substanw tially as set forth.

In a flour-sitter, the combination of a sifter-body, a reciprocatingstirrer upon the screen-bottom of the body and provided with a rodprojecting through the side of the body and provided with a stop uponsuch projecting portion, a movable handle engaging said stop toreciprocate the stirrer in one (lirection and to admit of the stirrerbeing independentl);r moved, a spring connected to the stirrer to returnit, and a sha-ft journaled in the body and constructed to reciprocatethe stirrer against its spring when revolved, substan tially as setforth.

i. In a ilonr-sifter, the combination of a sifter-bodyv having a rigid.handle-bail, a reciprocating stirrer upon the screen-betteln of the bodyand provided with an upward proj eetion and with a rod projectingthrough the body into the bail and there having an open hook, a movablespring-handle on the handlebail and having a pin engaging' said hook, aspring connected to return the stil-rer, and a crank-shaft journaled inthe sitter-body and provided with a cam en gaging the s1 irrerprojection, substantially set forth.

5. In a ilour-sifter, the combination of a siftcr-body having a rigidhandle-bail, a movable spring-handle on said bail, a stirrer,areturning-spring for the same, a rod upon the stirrer projectingthrough the walls of the sitter-body and connected to the spring-handleand bent at its middle to form an upward projection, and a cam-shaftengaging such projection, substantially as set forth.

In testimony that I claim the foregoing to be my invention I havehereunto set my hand this 13th day of March, A. I). 1805.
